Posting On Facebook Fan Pages

I've been posting messages using imacros on facebook fan pages.. but lately I've noticed that the posts with links in them dont show up in others feeds because I check it with another account.. I'm just looking for some information as to how that works? Is it the link that just makes it seem spammy and is filtered from the fanpage>? Thanks for any help!

usually if you're a new FB user, Fb will block your links.

fb patched it already i made a bot for this and now fb is blocking comments with link using your fanpage to post on other fanpage wall or post comment, with or without links you will be block for misusing it

fb is getting smart every day and making it harder for us but thing is this make money when you can and dont think that it will be long term just hurts less this way heehhehe
